2.0 MkIII golf GTI engine swap - wiring

[MissSpentYouth]

Hi All,

Just doing some research into a 2.0 mkIII golf GTi engine swap into a T25.

The mechanical side seems well documented and appears straightforward once you have got all the bits together and an easier task if you start with a diesel.

The electrical side seems less so. Most people seem to send off their salvaged engine bay wiring loom inc ECU connector to a guru who for about £350 pounds will remanufacture it to what is required. Has anyone done this themselves successfully and happy to share their findings ? 

Also most people seem to send off their ECU to have it remapped removing the imobilizer function. Has anyone managed to keep there's stock as I quite fancy having the imobilizer and can fit the golf key and pickup under the dash some where, I think you also need the clocks as well so I imagine there's a ton of wiring involved going this route.

Thanks Ben

it's dead easy , all you need is the full VW wiring diagram for the T3 and the donor vehicle, a bunch of various appropriate terminals/terminal housings and the crimping tools for them and bunch of free time, a logical mind and a deal of perseverance. Andy at Syncrosport used to do dash upgrade to use the later dash in our van but he's old now and has/had health issues so isn't really trading.
Or you pay someone who knows what they are doing and has the knowledge, parts, skills and tools for the 10 hours it will take them to do the job If it was me I'd use J's Garage as Jamie is a proper mechanic, runs a great garage, recently moved to new bigger premises with more staff (Jamie does the T3s stuff) and is in Wales
